Meningocele and meningoencephalocele are rare entities produced by herniation of cranial contents at the defective areas of the skull base, which may be congenital, spontaneous or traumatic. The condition may present as CSF rhinorrboea, nasal obstruction or even with meningitis. Managemenl of these basal encephaloceles with endoscopic surgery provides a direct view of the skull base and cause less morbidity compared with transcranial approach. Two cases have been reported here, first, a meningocele presented as a case of recurrent CSF rhinorrhoea and the second one, a meningoen­cepbalocele presented as recurrent meningitis, treated using an endoscopic procedure and reviews the literature regarding their management.

Background: Although endoscopic calcaneoplasty and retrocalcaneal debridement have been extensively applied to treat Haglund syndrome, evidence of the value of the endoscopic procedure remains to be fully established. Purpose/Hypothesis: The purpose of this study was to compare the postoperative outcomes and the amount of osteotomy between open and endoscopic surgery for the treatment of Haglund syndrome. It was hypothesized that endoscopic calcaneoplasty would lead to higher patient satisfaction and lower complication rates compared with open surgical techniques. Study Design: Cohort study; Level of evidence, 3. Methods: The following postoperative outcomes were compared between the open surgery group (n = 20) and the endoscopic surgery group (n = 27): visual analog scale for pain, American Orthopaedic Foot & Ankle Society ankle-hindfoot scale, Foot Function Index, Tegner score, Ankle Activity Score, and 36-Item Short Form Health Survey; postoperative complications; and duration of surgery. To determine the extent of resection, the authors compared the calcaneal height ratio, calcaneal resection ratio, calcaneal resection angle, pitch line, and Haglund deformity height between groups. The learning curve for endoscopic calcaneoplasty was also calculated. Results: There were no significant differences between the open and endoscopic groups on any outcome score. Two patients in the open group reported temporary paresthesia around the incisional site, indicating sural nerve injuries; no complication was reported in the endoscopy group. None of the parameters for extent of resection were statistically significant between the groups. The duration of surgery was 44.90 ± 10.52 and 65.39 ± 11.12 minutes in the open and endoscopy groups, respectively ( P = .001). Regarding the learning curve for endoscopic calcaneoplasty (6 surgeons; 27 follow-up patients; 9 patients lost to follow-up), the duration of surgery reached a steady point of 55.68 ± 4.19 minutes after the fourth operation. Conclusion: The results of this study indicated that the endoscopy procedure was as effective as the open procedure. The endoscopic procedure required significantly more time than the open procedure, and the duration of the endoscopic procedure was shortened only after the fourth operation, suggesting that it requires high technical skills and familiarity with the anatomic relationships.

Abstract Background Chondrosarcoma(ChSa) is a rare malignant tumor. But it’s necessary to discuss the clinical characteristics and treatments for ChSa of paranasal sinus and the skull base. Methods The clinical characteristics of ChSa of paranasal sinus and skull base in 10 patients (6 males and 4 females) from 2001 to 2017 were analyzed. They all underwent by endoscopic surgery . The patients’ age ranged from 18 to 47 years, with a median of 35 years. Clinical symptoms: stuffy, nose bleeding, runny, headache, diplopia, eye outreach limited, blurred vision and even blindness. Surgery methods：under nasal endoscopy, after the attachment sites of the tumors to normal tissues were confirmed, the tumors were peeled off along the clear boundary between the tumors and normal tissues, and the potential residual tumor tissues on bones were cleared by a drill. Results All patients were treated with endoscopic surgery，followed up postoperatively for 24 to 108 months, with a median of 36 months. 8 of 10 patients were no recurrence,2 were alive with tumor. Conclusion ChSa of paranasal sinus and skull base can be treated by nasal endoscopic surgery with good clinical results.

Abstract BACKGROUND Neuronavigation systems assist with spatial orientation during endoscopic transnasal skull base surgery, but they require a correlation of 3-dimensional (3D) views with 2-dimensional (2D) radiology studies. OBJECTIVE To outline an initial experience with a novel technology platform that provides intraoperative navigation using 3D reconstructions of patient anatomy for endoscopic surgery. METHODS A retrospective study of endoscopic anterior skull base and complex paranasal procedures was performed. Data from preoperative computed tomography and magnetic resonance imaging scans were fused to create 3D digital models of patient anatomy. Using the technology developed by Surgical Theater (Mayfield Village, Ohio), these reconstructions were designed to highlight particular anatomic regions of interest. The models were studied to guide the surgical approach and anticipate critical structures. The reconstructions were linked with the navigational technology created by Brainlab (Munich, Germany) during endoscopic surgery. A dynamic image of the reconstruction was displayed alongside a matching endoscopic camera view. These 2 views could be overlaid to provide an immersive, mixed reality image of the patient's anatomy. RESULTS A total of 134 cases were performed. The pathologies included tumors of the anterior skull base or sinonasal cavity, inflammatory sinus disease, and cerebrospinal fluid leaks. Specific anatomic structures, such as the internal carotid arteries and optic nerves, were chosen for enhancement. Surgeons felt that the technology helped to guide the extent of bony dissection and to identify critical structures. CONCLUSION We describe the first clinical series of complex skull base pathologies treated using a novel mixed reality platform.
